Marine Le Pen is challenging a court ruling linked to her conviction over misuse of EU funds, which could prevent her from running in France’s 2027 presidential election.
With President Macron unable to seek another term and support for the National Rally rising, the appeal could determine Le Pen’s strongest chance yet at the presidency.
If the ban is upheld, Le Pen has positioned her deputy Jordan Bardella as a potential successor, who polls suggest could be a strong contender in a future runoff.
